However, on the 1997 and 1998 900 turbo models (as well as the 99 9-3, except the Viggen model) there are 4 vacuum hoses that connect to the throttle body. You will need to remove the plastic engine cover to access these hoses. There should be a diagram of the vacuum hoses on an emissions label in the engine compartment of the vehicle.

*One hose goes from the throttle body to the turbo By-Pass Valve (BPV) located between the battery and the radiator.

*One hose goes from the throttle body to the fuel pressure regulator located on the fuel injector rail.

*One hose goes from the throttle body to a one-way valve (arrow on one-way valve points toward throttle body) and then to the Positive Crankcase Ventilation (PCV) fitting on the engine valve cover.

*One hose goes from the throttle body to the Manifold Absolute Pressure (MAP) sensor located on the strut tower brace.
